JOHN C. GOULD, OF CHICAGO, ILLINOIS.

FASTENER FOR THE MEETlNG-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 442,178, dated December 9, 1890.

Application filed April 14, 1890. Serial No.34z7,826. (No model.)

To all whom it may concern.-

I-ie it known that I, JOHN G. GOULD, a cit-i zen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specification.

My object in this invention is to provide a self-locking sash-fastener which is at the same time durable, simple, and easy of manufacture.

The novelty of the invention will be fully understood from the accompanying drawings and the following description.

The drawings show at Figure l a vertical section of the meeting-rails of two windowsashcs provided with my invention, the fast ener being shown in the unlocked position. Fig. 2 is a plan of the fastener with the parts in the same position as in Fig. 1. Fig. 3 is a plan showing the fastener locked, and Fig. l is a vertical section on theline 4 l of Fig. 3.

In said drawings, A represents the meeting-rail of the lower sash, and B the like rail of the upper sash.

G is a plate attached to rail A and supporting a pivoted latch D. This latch may be pivoted to said plate 0 in any suitable manner; but the construction which I prefer is illustrated at Fig. it, the latch being provided with a housing (I, which carries a downwardlyprojecting pivot d, and the plate 0 being provided with a hollow post c, into which said pivot (1 extends. A spring E for operating the latch encircles the pivot (1 within the post 0, one of its ends being secured in the postand the other in the pivot. 13y means of this spring the latch is rotated to the looking position automatically when it is released from its detaining device now to be described. \Vhen. the latch is moved to the unlocked or open position, which is done by taking hold of the handle portion (Z and rotating the latch to the position shown at Fig. 1, the tooth cl on the under surface of the latch engages with a corresponding teeth 0 upon the upper surface of the plate C as soon as the hand is withdrawn. In this manner the latch is automatically retained in the open position, as indicated at Fig. 1, until the meeting-rails are brought together, when the plate F upon rail B strikes the point (1 of the latch, which projects over the other sash-rail, and lifts the latch out of engagement with the tooth c. As soon as this has taken place the latch is free to swing to the locking position under the power of the spring E.-

I prefer to provide plate F with a raised ridge which will come in contact with the point of the latch, and upon which the latch will ride while moving to the locking position. This ridge tapers down to the level of plate F, as shown. The latch is slotted, as at I), in order that it may pass to either side of the stationary guard G, borne upon the plate F, and said guard is provided with an overhanging portion g, under which the part 71 of the latch will pass, and thus lock the sashes against vertical movement. The guard G atfords opportunity to bring the meeting-rails close together, as the slot D of the latch can be made to bear against said guard and produce this effect. A stop 5 is provided to limit the opening movement of the latch. The post 0 of plate 0 fits the interior of the housing (I, so that the latch may rotate on said post and be held thereby closely in its proper position, and supplements the pivotal function of the shaft or pivot d. The housing (Z covers the parts and keeps out the dust.

I make the spring E the means of holding the swinging latch down upon the-post of plate 0 and thus save the provision of a special fastening for that purpose. The spring is caused to perform this function by confining its ends in the manner shown, the one end being secured in an opening in the side of the post 0, which confines it against movementin either lateral or vertical direction, while the other end is secured in a dovetail groove (Z in the end of stud 11.

I Cltllll 1. The sash-fastener consisting of aspiring actuated swinging latch moving horizontally and attached to one of the saslrrails, means for detaining said latch in the open position with its point projecting over the other rail, and a projection or plate having a guard adapted to act with said latch in looking the sashes together, and also adapted to release the latch from said retaining device, substantially as specified.

2. In a sash-fastener, a pivoted latch provided with a housing (1 and a pivot on the interiorof said housing, in combination with a supporting-plate having a post to receive said pivot and enter said housing, and a spring actuating said latch and also serving to fasten the latch and plate together, substantially as set forth.

The sash -fastener consisting of the swinging pivoted latch and its supportingplate, said latch being slotted, as D, in combination with the plate F, having guard G, said guard Ghaving'the overhanging g, substantially as specified.

4. The combination of the pivoted latch D,

portion r slotted, as D, and its supporting-plate, with plate F, having the ridge f and the guard G, substantially as specified.

5. The combination, in a sash fastener, of a pivoted spring-latch D, having a tooth (Z and a supporting plate having a tooth 0, engaging tooth d to hold the latch open, both located upon one sash-rail, in combination With-a plate upon the other sash-rail for releasing the engagement of said teeth, substantially as set forth.
